A method for typing Shigella sonnei, using colicine production as a marker.
Infection with Shigella sonnei is the most common identifiable cause of diarrhoea in this country at present, and the absence of a satisfactory method of typing the organism has greatly hampered the study of its mode of spread. Bojlen (1934), studying the biochemical reactions of 1,786 Sonne cultures, isolated from 741 patients in Denmark, described four biochemical types based upon the ferment...
متن کاملColicine types of Shigella sonnei isolated in Hong Kong.
Two-hundred and twenty-five strains of Shigella sonnei isolated from sporadic cases of bacillary dysentery were subjected to colicine typing. The result showed that types 15 and 12 were the prevailing types in Hong Kong and two new types which did not fit in with the colicine patterns of the current types were observed. A marked increase in the numbers of strains concurrently resistant to chlor...
متن کاملColicin typing as an epidemiological tool in the investigation of outbreaks of Shigella sonnei.
Shigella sonnei has become the most frequently reported cause of shigellosis in the United States. Since Shigella subgroup D has no other serotypes, colicin production has been used as a basis for differentiating and identifying epidemiologically related strains. The results of colicin typing 115 cultures of S. sonnei from eight outbreaks of shigellosis occurring in widely separated regions of ...
متن کاملMacrolide-Resistant Shigella sonnei
Shigella sonnei UCN59, isolated during an outbreak of S. sonnei in January 2007, was resistant to azithromycin (MIC 64 mg/L). The isolate contained a plasmid-borne mph(A) gene encoding a macrolide 2 -phosphotransferase that inactivates macrolides. Emergence of the mph(A) gene in S. sonnei may limit usefulness of azithromycin for treatment of shigellosis.
متن کاملColicin typing of Shigella sonnei.
The colicin typing method for differentiating epidemic strains of Shigella sonnei was evaluated. Forty percent of the strains were untypable, but the method divides 60% of the strains into 15 established colicin types. The method has reasonably good reproducibility, but should not be interpreted with the same degree of confidence as some other characteristics such as serotypes. For this reason,...
